BOILER-FEEDER.

SPECIFICATION forming part of Letters Patent N0. 468,209, dated February2, 1892.

Application led April l, 1891. Serial No. 387,282. (No model.)

T0 @ZZ whom it may concern:

Be it known that we, HEINRICH RAUSEE and CHARLES WIEBEE, subjects of theEmperor of Germany, and ALEXIS SOKOLOFF, a subject of the Czar ofRussia, all of Moscow, Russia, have invented a new and Improvedioiler-Feeder, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedboiler-feeder which is simple and durable in construction and veryeffective and automatic in operation.

The invention consists of an ejector controlled by a float in the boilerand adapted to control the feed-pump.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to behad to the accompanying drawing, forming a part ofthis speciiication, in which the figure is a sectional side elevation ofthe improvement as applied.

In the boiler A is arranged a iioat- B, provided with auupwardlyextending hollow stem C, passing through a pipe D, held in acasing E, secured on the shell of the boiler, as plainly illustrated inthe drawing. Near the upper end of the stem C is arranged a disk F,adapted to engage with its periphery one arm of a bell-crank lever G,fulcruined in the casing E and carrying on its other arm a valve II,leading to an ejector I, of any approved construction, provided with theusual nozzle I and the cone-shaped mouth I2. Into the ejector I leads apipe J below the nozzle I', the said pipe .I being connected with acasing K, from which leads a pipe L to the valvechamber N of thefeed-pump N. In the valve-chamber N' is held a suction-valve N2. Overthe suction-pipe N3 and directly above the suction-valve N2 is arrangeda dischangevalve N4, connected with a discharge-pipe N5, leading to theinterior of the boiler A. The pump N is continually in operation; but assoon as the valve II is closed and the ejector I is not working thesuction-valve N2 remains seated, as the valve-chamber N is connectedwith the outer air by the pipe L, the casing K, and the pipe J,connected with the mouth I2 of the ejector. In the casing K is arrangeda float O, provided on its upper end with a valve C', adapted to beseated on a valve-seat K', formed in the upper end of the casing K atthe entrance of the pipeJ to the said casing. On the lower end of thelioat O is also secured a valve O2, adapted to be seated on a seat K2,formed in the lower end of the casing K and connected with an S-shapedoutlet-pipe K3, containing a ball-valve K4. Then the water in the boilerA sinks below the normal level, the float B slides downward with thefalling of the level of the wat-er, thereby moving the disk F on itsstem C into contact with an inoline on the bell-crank lever G, so thatthe latter is actuated and the valve II is raised off its seat. Steamfrom the boiler can now pass through the pipe D, the upper part of theCasin g Il, past the valve I-I, into the ejector I, so that air is drawnthrough the pipe J into the ejector and a vacuum is consequently formedin the valve-chamber N of the feedpuinp. As the latter is continually inOperation, water will rise in the suction-pipe N3, pass into the pumppast the valve N2, part of the water passing into the casing K, in whichthe float O is caused to rise by the incoming water until finally thevalve O seats itself on the seat K', thereby closing the pipe J, t-hevalve O`2 seating itself on the seat K2, so as to close the outlet ordischarge pipe K3. The pump N now operates in the usual manner, forcingthe water past the outlet-valve N4 into the outlet-pipe N, so that thewater is pumped into the `boiler A. IVhen the water has risen in theboiler A to the normal level, the doat B has risen upward with the waterand the disk F is again brought back to its former normal position abovethe incline on the bell-crank lever G. The valve II is thus again seatedon its seat and the ejectorlstops working. As soon as the ejector stopsworking the pressure in the pipe J on the valve O causes the iioat O' tomove downward, the said valve O having a larger area than the valve Assoon as the valves O and O2 are unseated the water in the casing K iiowsthrough the outlet-pipe K3, whereby the air entering the pipe J againpasses to the valve-chamber N', so thatthe valve N2 remains seated onthe ICO further working of the pump and no water is' the cylinder, theformer through the mouth l2 andV pipe .I and the latter from the casingK, as the vacuum above the valve O ceases as soon as nthe steam is shutoff from ejector i by the seating of valve H, as above mentioned. Thefloat O consequently sinks and the pump only -sucks in air throughejector I, -pipe- J, casing K, and pipe L until the ejectoris againactuated and produces a vacuumV above the valve 0. Y

In case the valve'II or otherparts described are out of order and thepump should not force the necessary amount of Water into the boiler, asabove described, then the water in the boiler will sink to a dangerouslevel. In order to warn the operator of the danger, the following deviceis provided: A second bellcrank lever P is pivoted in the upper end ofthe casing E and is provided on its vertical arm with an inclinearranged a suitable distance .below the incline of the bell-crank leverG, arranged opposite the lever P. The horizontal arm of the bell-cranklever P carries a valve Q, connected with a Whistle R,so that when thewater sinks to a dangerous level in the boiler the doat B movesdownward, and the disk F, acting on the bell-crank lever I), causes .thevalve yQ to be unseated and steam is Afree to pass from the boiler tothe whistle R to sound the same, thus giving the signal.

To prevent too much water Ifrom being pumped into the boiler A by thefeed-pump N, the following device is provided: 0n the stem C is arrangeda valve S, adapted to be seated on a valve-seat D', formed on the lowerend of the pipe D, establishing communication between the interior ofthe boiler A and casing E, as previously described. New when the waterrises to its maximum level in the boiler A the valve S seats itself onthe seat D of the pipe D, so that steam cannot pass to the casing E andto. the ejector I, so -that the operation of the pump N ceases, aspreviously explained.

In order to permit the float B to fall with the receding water in theboiler A, a valve T `is provided formed on the extreme upper end of thehollow stein C and adapted to be seated on a valve-seat E', arranged inthe cap of the casing E. Vhen the valve S is seated on its seat, thevalve T is likewise seated on its seat E. Now as soon as the waterrecedes in the boiler A the steam passing through the apertures C in thehollow stem C to the valve T presses on the latter, so that the pressureon the valve S is equalized and the float B is tree to sink with thefalling Water. It will thus be seen that the boiler-feeder is completelyautomatic in operation, prevent-s a dangerous iilling ot the boiler, andalso gives a signal in case the water should sink 'to a dangerous level.v
